Detecting PHP2Shell remote code execution with Wazuh

REVSTEALER is a Windows information stealer that targets browser credentials, cryptocurrency wallets, gaming accounts, and other sensitive data. Researchers have documented its distribution through game-cheat lures and applications disguised as legitimate software. The malware uses environmental checks to evade sandbox analysis and may terminate when it detects specific regional locales. It also retrieves fallback command-and-control […]

Extended Berkeley Packet Filter (eBPF) is a Linux technology that allows sandboxed programs to run in the Linux kernel. The kernel manages system memory, running processes, and hardware resources. eBPF supports application performance monitoring, network traffic management, and security monitoring without requiring changes to the kernel source code. eBPF programs run when specific events occur. […]

Kubernetes workloads introduce security risks when deployed with excessive privileges, unsafe configurations, or settings that do not meet organizational requirements. Admission controls evaluate resource requests before Kubernetes creates or updates resources. These policy decisions provide useful security telemetry by identifying non-compliant workloads, rejected deployment attempts, and configuration changes. Kyverno is a Kubernetes-native policy engine that […]

Privilege escalation is the process by which an attacker gains permissions beyond those assigned to their current account. On Windows endpoints, threat actors who gain initial access as a standard user may exploit misconfigurations to obtain administrator or NT AUTHORITY\SYSTEM privileges. With elevated privileges, an attacker can disable security controls, access protected files, dump credentials, […]

Web application firewalls (WAFs) secure web applications by inspecting HTTP traffic and blocking malicious requests before they reach backend services. They help protect applications from attacks such as SQL injection, cross-site scripting (XSS), path traversal, command injection, and other threats covered by the OWASP Core Rule Set (CRS). Coraza is an open source WAF engine […]

Attackers often abuse legitimate Windows features and applications to execute malicious code, steal credentials, establish persistence, and evade security controls. Detecting these behaviors early helps security teams identify suspicious activity before it leads to further compromise. Microsoft Defender Attack Surface Reduction (ASR) rules help protect Windows endpoints by restricting behaviors commonly abused by malware and […]

AWS access keys are credentials that applications, users, and automation tools use to authenticate to AWS services through APIs. Each key consists of an access key ID and a secret access key. The associated IAM identity determines which AWS resources and operations the credentials can access. When access keys are exposed through public repositories, build […]

Langflow is an open source, low-code platform for building and deploying AI-powered agents and workflows. These workflows, called flows, define how AI models, prompts, and other components interact to process a request. Organizations can publish flows as HTTP endpoints, allowing applications and users to interact with them remotely. Exposing these endpoints to the internet increases […]

SUID (Set User ID) and SGID (Set Group ID) are special Linux file permission bits. They allow a program to run with the privileges of the file owner or group rather than the user who launches it. Legitimate binaries such as passwd, sudo, and chage rely on these bits to perform privileged operations safely. Attackers […]

Kubernetes is widely used for orchestrating containerized workloads. Securing a Kubernetes cluster requires configuring control-plane components, worker nodes, and workloads according to security best practices. As Kubernetes clusters evolve through upgrades and operational changes, maintaining secure configurations becomes increasingly challenging. The CIS Kubernetes Benchmark provides security recommendations for hardening Kubernetes clusters, including control-plane components, worker […]

Security teams process large volumes of alerts each day, which makes it difficult to identify recurring threats, prioritize incidents, and respond consistently. While continuous monitoring is essential, organizations can also benefit from scheduled summaries that consolidate alert activity over a defined period. These reports help analysts recognize patterns, surface recurring issues, and track risk trends […]
